I've got a plug-in car charger in my garage that uses a dryer-type plug. It was installed by a licensed electrician and is connected to a sub-panel that he also set up. Since the garage requires GFCI breakers by code, that's what was installed. The problem is that my charger has its own built-in GFCI, which causes issues with the breaker GFCI, leading to it tripping about five times a week. I've read this is a common issue, and the suggested fix is to use a non-GFCI breaker, but I can't do that due to code regulations. Is there any other solution to this? I really don't want to keep waking up and finding out that my car hasn't charged overnight, especially before I have a long drive ahead.

One option could be to hard-wire your charger instead of using the plug-in model. This way, it won't have the GFCI inside the charger, and you'll be able to draw more amperage, potentially up to 48A instead of being capped at 40A with the NEMA14-50. Just something to consider!
